LANDER, a subject of the King of Sweden, residing at lii'inneapolis, in the countyofHenof Minnesota, have lnvented and useful Car-Stopping Device, of

following is a specification.

invention relates to railway appliand the object is to provide an efficient for stopping a railway car at any desired place on a track where it is intended stopped during switching operations without the expense of keeping a brakeman 1 each car for operating the brakes. The d ice is especially adapted for the so-called switching, in which one or more cars n by the momentum along upon some and be there stopped by the brakes.

d of thus employing a bralreman on or my device enables one man on the our 1 car yard to stop any number of etemine places on the track.

2 2 is a left hand Fig. 3 is a top view of z e is a section on the line tid 3 with the car wheel omitted. to the drawin by reference 5) designates an ordinary rail of a i which. runs ordinary car 1 inner side of the tread Us of an angle 8 1S placed upon and the vertical flange Q irected toward the 2 both of its'fianges 10, so as to make the A al without giving it a z ish device along the rail. if end of the angle "bar is formed known that 1, Emma HUGO WAif' Wen a "msh by an engine and then left raving a guiding flange 6* with a hollow head 11, having a segmental face 12 arranged to meet the face of the wheel 5.

In said face 12 is a large aperture 13, in which is loosely fitted a segmental faced block 14, whose lower end is pivoted at 15, and the upper end is provided with an ofl set extension 16, which takes against the inner side of a flange or ledge 17 when the curved face of the block projects outward a considerable extent beyond the face 12 of the head. In said position the block is normally held by a strong coil-spring 18 placed inside of the hollow head. 19 is a handle for taking hold of in moving and placing the device in position. It also serves to brace the head 11. In the use or operation of the device the operator, knowing-the place where the car is to be stopped, places the device on one of the rails in the position shown in the drawing, and as one of the wheels of the car rolls upon the flange 8 it presses said flange firmly against the face of the rail and thereby prevents sliding of the device. The wheel then strikes the block 14: and compresses the spring 18 more or less according to the impact; in most instances the wheel may reach the face 12 of the head, but whether it does or not, the spring is supposed to re-act and, after serving as a cushion to deaden the sound and take the blow of the wheel and stop the car, to push the car with the wheel ofi' from thd device, so the latter may he removed to other parts of the track for likewise stop ping other cars. Car tracks are hardly ever so much inclined that a car will start from its own weight, but should such a case be found, the device may be left on the rail in such a position as to prevent accidental motion of the car, or the same operator may set the brake on such a car and then remove the device.

One man with a few of these devices may thus do the work of several brakemen.

What I claim is: 1. In a device of the classdescribed, angle bar having both flangesioeveled at one end and at the other end a head with a segmental face arranged to meet the face of ar approaching car wheel, said head being hol- 10w and'having in it's segmental face an aperture, a segmental-faced block pivoted with its lower end in said aperture, a spring in the hollow head tending to swing the block outward in the aperture, and means for stopping the outward swinging movement of the upper end of the block when its face is some distance beyond the face of the hollow head so as to meet the face of the 10 backward to set the device free after it has 15 stopped the car. I

In testimony whereof I affix my signature.
